Simple spell for restraining its target. Ropes are most likely made of a magical material and would vanish after its use is done. Unsatisfactory against a large group of people, as it would cost too much energy for the spirits involved.

Mailman: "Hahaha! You ain't gonna shit right for a week!"
Your Grandma: "Actually I haven't enjoyed regular bowel movements for 20 years since this damn Atkins diet has been binding me like crazy. I've got more shit in me now than a port-o-john at the town chili festival!"
Mailman: (loses his lunch) "TMI, you old wench!"

To "bind" a key on ones keyboard to preform a specific task when struck. Normally preformed in console baised PC games such as Counter-Strike. This is generally used to allow the player to say entire sentences with the stroke of 1 bound key.

Player brings up his console and types... bind \ "say LoL we pwned you wOoT!".
After this whenever the player strikes his \ key his character will say "LoL we pwned you wOoT" in his chat menu.
